What organization is WPC?

 WPC, which stands for Wireless Power Consortium, was established in 2008. It is an open and collaborative standards development organization comprising over 400 member companies. WPC is the leading authority in the mobile device industry for standards such as "Qi" and the creator of the "Ki" wireless kitchen standard. The organization is dedicated to advancing global compatibility and safety in the use of wireless charging technology.

What is Qi Wireless Charging?

Qi wireless charging is an open standard for wirelessly powering electronic devices. Developed cooperatively by leading global companies, it uses inductive charging technology to transfer power through electromagnetic fields. Any device sporting the Qi logo is compatible with Qi charging surfaces, irrespective of brand or manufacturer. This universality makes Qi a cornerstone in today's tech ecosystem.

 

The Qi Standard - Working Principle

 

At its core, Qi wireless charging relies on inductive charging. It involves two coils: a transmitter in the charging pad and a receiver in the device. When placed near each other, an electromagnetic field is generated, allowing the transfer of power. This process, while technical, is made user-friendly and is exemplified in products like Mokin's wireless charging station.

The most mature and widely adopted approach is electromagnetic induction. Its fundamental principle relies on the electromagnetic induction concept, similar to that of a transformer. There are two coils, one at the transmitting end and the other at the receiving end. The primary coil is energized with a specific frequency of alternating current, which induces a certain current in the secondary coil through electromagnetic induction. This process effectively transfers energy from the transmitting end to the receiving end.
